About this Validator
This tool validates Norwegian Value Added Tax Numbers according to official requirements.
The validator checks if a given MVA number follows the correct structure and verifies its modulus 11 check digit.
This validation only confirms if an MVA number follows the correct format. It does not verify if the number is actually registered with Norwegian authorities.
